what timeframe (morning, early afternoon, evening, night etc) do you recommend taking the Arch boat tour and Chicago 360 for the best experience/views?
Both the Architecture Boat Tour and the Chicago 360 offer incredible views, and the best time to experience each will depend on the kind of atmosphere you're looking for. Here are some suggestions for optimal times for each tour:
Architecture Boat Tour: The best time for this tour is typically in the late morning or early afternoon. The light at this time tends to be optimal for viewing and taking photos of the iconic buildings along the Chicago River. Morning tours (around 10:00 AM or so) tend to be a bit cooler and quieter, especially before the crowds build. Early afternoon tours are ideal for clear skies and better lighting for photos.
Chicago 360 (formerly John Hancock Observatory): For this, the evening or night time is the best to enjoy the stunning views of the city's skyline lit up at night. From the 360 Chicago observation deck, you'll get an unparalleled view of the city’s twinkling lights, Lake Michigan, and the surrounding areas. If you want to see the city in full splendor, a sunset visit, followed by twilight and evening views, offers the most dramatic experience.
In Summary:
Enjoy your time in Chicago – both of these experiences are not to be missed!
